If you add a list field (any data type), set it to multiple and provide a default value, it is impossible to deselect all options for the field. The field system sees that that no values are supplied and supplies the default value on save. The default value populates the form for the field, so if the user explicitly unchecks them, the field system should not inject it's own defaults instead.
Indeed, I can reproduce with radios, checkboxes, but actually also for any field type and widget (e.g simple textfield widget for text or number fields).
1. Set a default value on a field
2. Go to the creation form for an entity using that field
3. Remove the pre-filled value (FAPI #default) and leave the field empty, save
4. The entity has the default value for the field.
This happens in field_default_insert(). Since #392696: Save default values on insert, default values get added on "entity insert" when the incoming $entity has no $entity->field_name property. That was to save default values on programmatic entity saves.
Later on, the 'Translatable fields' patch changed the condition, and default values get added also when
isset($entity->field_name[$langcode]) && count($entity->field_name[$langcode]) == 0
Yet $entity->field_name = array($langcode => array()) is exactly what comes out of any field that was left empty.
I cannot say I specifically remember the reasoning behind the code added by the TF patch, but it looks like we should rather check for !isset($entity->field_name[$langcode]).
We'll also need tests for this :-/.
